If it is hard to start, you may want to have someone check the fuel pressure.

SOURCE: 2001 Mercury Grand Marquis hesitation and jolting from 35-45 mph

Sure, the more the throttle and the longer its open the more gas is being injected so if the spark is not there it will spotter. I think you have nothing to loose with an ignition tune-up. It'll be more economical than taking it to a mechanic and still ending up with the same problem. You should change the fuel filter also it could be clogged and there is'nt enough fuel delivered at these speeds. You can also try a fuel injector cleaning solution the kind you pour in the gas tank. This might work for you.

From the 1997 Mercury Grand Marquis 4.6L SFI 8cyl repair manual, the Flasher is located behind left side of instrument panel. The turn signal and emergency flashers are attached to the interior fuse panel. They are replaced in the same manner as the fuses and circuit breakers.

Code p0304 misfire e 320 mercdes 1997 when you start car vibrates and when you are at stop sign. solution please

A code P0304 may mean that one or more of the following has happened: Faulty spark plug or wire Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector, Burned exhaust valve, Faulty catalytic converter(s), Running out of fuel, Poor compression, Defective computer.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs/wires). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if equipped). Otherwise, check the coil packs. Sometimes the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your catalytic converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
